Abstract The genus Chondrocyclus Ancey, 1898 contains the majority of southern African
members of the Cyclophoridae, a large family of operculate land snails. We present the first …

ABSTRACT A new species of Diplommatina Benson, 1849 from Sikkim, Northeast India is
described based on shell morphology. This new species is found to be distinct in its …

Pacific island land snails exhibit exceptionally high species diversity, morphological
